abled at one or more points when desired, and the totalizer could thenbe used for adding in a plurality of columns. It has also been proposedto construct a totalizer settable at will into a condition such that,when the totalizer was moved into engagement with its actuators, acertain group of its wheels would be held back out of engagement, butwithout disabling the transfer. The wheels thus restrained were notaffected by the difierential movements of the actuators, but wereavailable to register amounts transferred to them from wheels of lowerorder. Machines equipped with such totalizers as above referred to canbe set up by the operator so as to adapt them for different uses. It isan object of the present invention to improve not only the means forsplitting a wide totalizer, but also the means for disabling portions ofit altogether, leaving the actuators for the disabled wheels availablefor other uses. This is especially useful in instances where saidactuators are also associated with, or themselves constitute, typecarriers, and particularly where said type carriers bear alphabetic orother types in addition to numerals. Thus, actuators associated with thetotalizer or with some part thereof. may be used at one time for addingand at another time actuators associated with disabled totalizer wheelsmay be used for printing text including alphabetic text or otherdesignatory matter while still using a portion of the totalizer forcomputing. To provide for this flexibility of use is one of the objectsof the invention.

Another object of the invention is to render the totalizer more certainto operate correctly in a respect which will be pointed out.

To the above and other ends which will be apparent from the followingspecification, the invention consists of certain features of construction and combinations and arrangements of parts, all or which will befully described herein and particularly pointed out in the claims.

In the specific instance illustrated in the drawings, the invention isshown embodied in a punched card tabulating machine of the sortdescribed and claimed in the application for Letters Patent forTabulating and accounting machines, filed November 13, 1937, by W. W.Lasker, Jr., executor of the will of W. W. Lasker, deceased, and J.Mueller, S. N. 174,354; in the corresponding British patent of RemingtonRand Inc., for Statistical machine, No. 522,562, accepted June 20, 1940;and in the application for patent for Tabulating and accounting machine,filed February 1, 1940, by J. Mueller, S. N. 316,739. Except ashereinafter explained, the machine fragmentarily illustrated anddescribed herein, may be as described in said patent and applications.

As shown generally in Fig. 1, the machine comprises a base section 30,and mounted on it a head section 3|. The base section is constructedsubstantially as described in the patent to W. W. Lasker, No. 2,044,119,dated June 16, 1936, and is the same as has been in use in Powerstabulators for a number of years. Punched cards are fed from a hopper32, by picker 33 and feed rolls 34,

' and they rest on a flanged cross bar 65.

into a sensing chamber in the base of an upper pin box 35, from whichthey pass into a receptacle 36. The sensing pins 31 are in a lower pinbox 38 which is reciprocated by eccentrics 48 on the motor driven mainbase shaft 4|. They elevate set pins 42 in the upper pin box 35, andthrough them operate Bowden wires 43 in a translator 44. In the headsection 3|, the Bowden wires 43 displace code or "permutation bars 45which, in turn, control stops 46 for arresting the combined typecarriers and totalizer actuators 41. The latter are guided on rods 48,are moved upward against the stops 46 by springs (not shown), and aremoved down to normal position by a restoring bar 58. As far as thepresent invention is concerned, the actuators 41 may be reciprocatedand'controlled by any suitable means. The head section has a rear driveshaft and a front drive shaft 52, geared to rotate at the same speed asthe main base shaft 4|. The restoring bar 50 is reciprocated by cranks,one on each end of the shaft 5|, which cranks drive pitmans 53 (Fig. 3)with a motion modified by certain guide discs in a manner not necessaryhere to be explained.

In the machine of the prior disclosures, there is a long continuousseriesof the actuators 41, each of which carries a series of types 59,including both numeric and alphabetic types (Fig. 11). A number oftotalizers may be placed in front of said actuators in two tiers,mounted on two dove-tail shaped frame bars 54 and 55; and theconstruction is such that a totalizer may be a link 68 with a bell-cranktransfer pawl 10, pivoted at 1| to the left hand face of the next lever68 to the right, (Fig. 8) and cooperating in ausual way with a transfertooth 12 on the wheel 56 on that lever. When said wheel turns from 9 to0, said tooth rocks the pawl counterclockwise, withdrawing the dog 66and permitting the left hand lever 60 to rise at its rear mounted in anydesired position on either of said bars so as to be actuated by anydesired succession of the actuators. In the assembly of each individualmachine, totalizers are so mounted in number and location appropriate tothe use to which the particular machine is'to be put. The totalizerillustrated in the drawings is adapted to this situation, though theinvention, as to most of its features, is applicable to other machines.The specific totalizer illustrated will be described in detail.

The totalizer may be of a width greater than is likely to be needed fora single number, and p it is so constructed that it can be split at adesired point or points, so as to divide it in effect into a pluralityof totalizers, each comprising whatever number of register wheels isrequired by the work. As shown, and preferably the totalizer can besplit, by the operator of the machine, at any point in its width hedesires. The drawings were made from a totalizer of a width of fortydenominations. The totalizer wheels 56 (Fig. 6) are each journaled on abearing 51 riveted to the left hand face of a sheet metal lever 60which, with certain differences to be described, resembles leverscontained in the totalizers of the prior disclosures. In Fig. 6 thesection is taken on the left face of one of these levers, and the wheel56 and cooperating parts guided in upper and lower comb bars 63 and 64,

When the wheels 56 are in mesh with the racks 41, the levers 60 areindividually spring urged to swing upward at their rear ends. .Eachlever is normally held down by a transfer dog 66 engaging a shoulder ofthe lever. The dog 66 is urged into engagement by a spring 61, and isconnected by end. 'The wheel 56 on said left hand lever is thus movedindividually along its actuator 41 (lengthwise of said actuator) adistance to turn said wheel one tooth, when said lever is arrested by ashoulder 13 thereof striking the comb bar 63. Each wheel 56 is held,when out of mesh, by a detent lever 14 pivoted to the lever 68 at 15,and urged against the teeth of the wheel by a spring 16. As thus fardescribed, the register wheels, their levers 60 and the transfer anddetent devices, are all substantially the same as the upper set of suchdevices in the totalizer of the prior disclosures. The transfer dogs 66are pivoted on a rod 11 seated in a comb bar 18.

The comb bar 6| is a part of a frame which swings rearward and back tomove the wheels 56 into and out of mesh with the racks. Said frame maybe variously constructed. As shown, its principal member consists of around rod (Figs. 6, 9 and 10) having a longitudinal cutout with oneradial wall against which a flange of the bar 6| is secured by screws8|. At its ends it has eccentric trunnions 82 jourialled in bearings inthe staationary base casting 83 of the totalizer unit, said bearingsincluding journal caps 19. The flange on the bar 6| extends only thelength of the thick portion of the member 80, the ends of said barprojecting a little beyond the base member 83. The member 83 isdetachably and adjustably secured to the dovetail shaped bar 54 or 55 inabout the same manner as in the prior disclosures, viz., by a dovetailundercut fitting the-rear edge of the bar and clips 19 screwed tightagainst the forward edge of the bar.

The frame of the totalizer proper comprises right and left hand frameplates 84 (Figs. 5, 8 and 10) which plates are rigidly connected by thecross bars 63, 65, and 18. The bar 65 is supported at its ends bybrackets 85 secured to the plates 84, and the comb 64 is supported fromthe bar 65 through a bar 86. Said bar 86 and the comb 18 are made fairlyheavy for stifiness on account of the width of the totalizer. Near theirfront ends the frame plates 84 occupy the extreme right and left endslots of the comb bar 6| (Figs. 9 and 10). Each has a stud .81 pivotedin the groove of said bar and retained in place by a clip 88 secured bya screw to the end of the-bar 6|. The rear ends of the frame plates 84are supported by links 90 pivoted thereto and to the base casting 83.The whole construction is such that when the member 80 is rockedclockwise as viewed in the drawings, the totalizer, including the levers60 and the framework in which they are guided, moves as a whole rearwarduntil the wheels are properly meshed with the racks. The motion islimited by stop plates 92, one screwed to each side of the base 83,arresting lugs 93 depending from the frame plates 84. The totalizer ismoved to its forward position by springs 94 (Fig. 5).

'I'he rocker comprising the bar 6| and shaft 88 also includes at eachend a plate-like lever 95 which '(Figs. 9 and 10) is secured by a screw96 against the end of the trunnion 82 and which has a fork embracing theend of the bar 6 so that the lever and said bar are keyed together torock in unison. Each lever 95 has a forwardly directed arm which isconnected by an upright link 91 to a lever 98, pivoted on a transverseshaft 99 supported by the frame plates 84. The rear arms of the levers98 are connected into a bail by a rod I which overlies the forward endsof the detent levers I4. When the rocker is rocked clockwise to engagethe totalizer wheels with the racks, the rod I00 depresses the forwardarms of said detents and lifts them out of the wheels. A similarconstruction was described in the prior disclosures.

As in the Mueller application, S. N. 316,739, two levers IOI pivoted tothe outer faces of the frame lates 84, are connected by a bail bar I02overlying the levers 60, each lever IOI being urged clockwise by aspring I03 and'having an arm underlying the bail bar I00. When thetotalizer is shifted rearward to mesh the wheels, and the bar I00descends, the bar I02 is raised away from the levers 60, leaving themfree to swing upward in case of transfer. When the wheels move out ofmesh and the bar I00 rises, the springs I03 depress the bar I02, toassure that any elevated lever 60 is returned to normal.

Spring pressure is applied to the totalizer levers B0 to move their rearends upward to transfer the tens, in the same manner as in the priordisclosures. Each of said levers forward of its pivot 62 has pivotedthereto at I04 a bellcrank I05 which is urged clockwise (Fig. 6) by aspring I06 connected to an arm of the bell-crank and to the end of thelever 80, the motion bein limited by a lug I01 formed off from saidlever. A roller I08 at the forward end of the bell-crank, underlies achannel bar IIO secured to a cross bar III. There are two of these crossbars, one for the upper and the other for the lower tier of totalizers,and they are connected together at their ends into a rigid rectangle byvertical bars IIZ (Fig. 2). Each of the bars H2 is pivotaliy mounted ontwo parallel rock arms or levers I I3, pivoted at II4 to the right andleft hand main frame pieces II5, respectively, of the head section ofthe machine. The lower lever I I3 of each pair carries a follower rollerH6 bearing against a cam III. on the front drive shaft 52, against whichearns the parts are held by springs H8. The cams are so designed as todepress the bars III just after the totalizer wheels have been engagedwith the racks and to allow them to rise, deenergizing the springs I06in time to permit any operated levers 60 to drop down to normal positionwhen the wheels are out of mesh with the racks.

In the prior disclosures the bell-cranks I05 were on the upper ones oftwo sets of levers like the levers 60, so that the rollers I08 boreagainst the under surface of the bars III themselves. The present levers60 occupy vertically about the position of the former lower set, and themembers IIO are inserted to take up the space thus created between thefollowers I08 and the bars III. It is contemplated that it may in someinstances be desired to employ both the present adding totalizers andalso the former adding and subtracting totalizers side by side in thesame machine. It is, therefore, preferable that the member I it) be onlylong enough to cover the followers I08 of the present totalizer (to thenumber of forty in the specific instance described) leaving the bars IIIotherwise in condition for use with the former totalizers.

The totalizers are moved into and out of engagement with their actuatorsby the rocking of two shafts, viz., a. shaft I20 for the upper tier anda shaft I2I for the lower tier of totalizers. these shafts and the meansfor operating them and for controlling their operation being identicalwith those of the prior disclosures. One of the levers (Fig. 5) (theright hand one, as illustrated) has a link I22 pivoted thereto at I23,said link being pivoted at I24 to a lever I25 fast on a stub shaft I28Journaled in a boss at the base casting 83. The lever I25 is operated bya link consisting of a rear section I21 and a front section I28, saidsections slidably connected together by slots and headed pins I30 and bystifl springs I3I tending to maintain the compound link at its maximumlength. In case a totalizer wheel tooth collides with a tooth of theactuator, the link can yield, stretching the springs I3| instead ofinjuring the mechanism. An arm I32 fast on the rock shaft I20 or I2I hasa stud I33 playing in a closed slot I34 in the forward part of the link.When the shaft I20 is rocked clockwise, or the shaft IZIcounter-clockwise, the stud I33 acting on the link I28, I21 rocks thelever I25 which, through link I22, rocks the rocker 95, 80, BIclockwise, moving the totalizer rearward until arrested by the stops 32thus bringing the wheels into mesh with the racks (Fig. 4). The partsare so designed that in this movement the radius I26, I24 of the leverI25, and the axis I24, I23 of the link I22, have the action of a toggle,acting on the lever 95 with an increasing leverage and a deceleratedvelocity, so that the totalizer is brought to its engaged position witha sufficiently powerful pressure and is brought to rest gently withouttoo much jar. In its final position the toggle lacks enough of beingdead centered to assure that the springs 94 can restore the parts whenthe arms I32 return to their forward positions.

In order to provide for disabling the totalizer in its entirety whendesired, the slot I34 is made of such length that the stud I33 can moveidly in it without operating the link, and the surplus length is coveredby a displaceable interponent. As here shown said interponent consistsof a sheet metal piece I35. pivoted at I36 to the link section I28 and,when in active position, having its front end covering a portion of theslot I34 and lying in the path of the head of the stud I33 andcommunicating the motion of said stud to the link, as shown in Fig. 4and in the lower totalizer in Fig. 5. The interponent I35 can, however,be swung by hand to the position shown in the upper totalizer of Fig. 5,where it is out of the path of said stud. In the setting illustrated inFig. 5 when the shafts I20 and I2I are rocked. the lower totalizer willbe brought into engagement and not the upper. The interponent isinfinenced by a spring I31 so disposed that it tends to retain saidinterponent in either of its positions, which positions are defined bytwo arms I38 of said interponent being arrested by the pin I39 to whichthe spring is connected.

In operating the adding and subtracting totalizer of the priordisclosures, arms similar to the arms I32 had the double duty of firstreversing the totalizer from one sign to the other, on occa sion, andthen moving the totalizer into engagement, so that said arms have alonger stroke than is required for the present totalizer, which accountsfor the 10st motion between the stud I33 and the interponent I35indicated in Fig. 5. In another machine such lost motion would, ofcourse, not be necessary.

In order to provide for splitting the totalizer at any desired point orpoints and for disabling any desired denominational elements of it,means are provided whereby a lever 66 may be set bodily forward of itsnormal position relative to other such levers, and secured there, thusdisplacing the wheel 55 on said'lever away from its actuator 41. In theinstance illustrated, each lever 66 is provided with two studs 62 (Figs.6 and 9) one behind the other, the forward stud resting in the notch inthe bar 6| when the element is in use. The forward end of the lever maybe lifted by hand and the lever be drawn toward the front of the machineand the rear stud seated in the notch as shown in the middle one of thethree levers in Fig. 9. This locates that totalizer wheel 55 so farforwardthat it does not engage its rack 47 when the bar BI is swungrearward, thus leaving that rack and type carrying bar entirely free forother use such as to print either alphabetic characters or numbers notto be added.

In order to prevent accidental displacement of the studs 62 from the bar6i, a locking flap or ball I46 (Fig. 6) is provided, having at its endsears pivoted on the cross rod 69 and urged by a spring MIcounter-clockwise to its locking position where it is arrested by earsI82 (Fig. 8) striking the front edges of the frame plates 84 The loweredge of this bail stands just above the upper edges of the levers 65.When it is desired to change the setting of one of these levers, thebail I46 is swung by hand clockwise out of the way.

may be located at any desired positions, and all other positions of thetotalifier may be disabled entirely, the Wheels never engagingtheactuators. The bars 67 coordinated with these wheels may, therefore, beutilized for printing any desired numbers or text or for adding onanother totalizer on the other bar 5 8 or 55. If the unused wheels werepermitted to engage the actuators, such printing would cause ahodge-podge of numbers to be rolled into them, resulting in the printingof meaningless totals. Also, the spacing of the types on the type bar isonly half that of the rack teeth, and alphabet types are interspersedbetween the numeral types, as shown in Fig. 11. When, for example, a bar41 is set to print an E,"

a tooth of the rack stands directly behind a tooth of the totalizerwheel 55, and if it were sought to move said wheelinto engagement, theteeth When a lever to is set forward in its disabled position, it rocksclockwise the transfer dog 65 which engages it. The link 68 for this dogis connected with the transfer pawl ill of the next lower order, andwhich may still be in active condition. In order to permit of thisswinging of the dog 66 without disturbing its pawl I6, said dog isconnected with its link 68 by pin and slot, the pin moving to theforward end of the slot when the dog is swung as described.

In order to prevent swinging movement of a lever 56 which has beendisabled as above described, each such lever has a finger I 33 made atits under rear portion, and projecting forward in such position that,when the lever is set inactive said finger comes under the flange on theframe bar 55, as shown in Fig. 9, and locks the rear end of the leverdown.

The setting of a lever 60 to its forward position to produce a splitbetween two sections of the totalizer, acting through link 58, unlatchesthe dog 66 for the next lever 60 to the left. The pawl I0 then rests ona stud 69 on lever 50, to prevent said pawl from dropping down. Saidlever 60 then becomes the units lever of the left hand section, and itwill not be required to rise for transferring. In order to lock thisunits lever down, the following means are provided (Figs. 6, '7, 8, and9). Near its rear end, each lever 60 has an ear I44 projecting from itsright hand face, and an ear I45 from its left hand face, said ears sodisposed that when one of the levers is set to its forward inactiveposition, its ear I45 lies on top of the ear I44 of the next lever 60 tothe left. As the inactive lever is locked down at M3, its ear I45 locksdown the units lever at its left. This is illustrated in Fig. 9 and alsoin Fig. 7 where the third lever from the left has been drawn forward,bringing its ear I65 into the plane on which the section is taken.

Within the range of the, say forty places, of the totalizer, addingcolumns of any desired width would collide. This is obviated by settingthe wheelback as described, so that it never engages the rack. Anydesired denominations of the totalizer may be temporarily put out of usein the manner described.

A further improvement in the totalizer resides in the provision of alock to assure that the levers 66 do not rise in total takingoperations, In total taking, the wheels 56 are in engagement with theracks 31 on the up-strokes of the latter, and each said wheel and rackis arrested by the transfer lever being struck on its abrupt edge by thetransfer tooth 72 on the wheel. It has been found in practice that inrapid operation, the vibration set up by this blow may occasionally jarthe dog 66 loose from the. shoulder on the lever 60, allowing the latterto rise, thus causing the type carrying rack to move upward too far. Inorder to make this misoperation impossible even at high speed, a bailbar I46 (Figs. 4, 5, 6, and 8) normally stands as shown in Fig. 6 withits lower edge just back of the upper edges of all of the levers 66; butin total cycles this bar is swung forward so as to stand above saidlevers and positively to, prevent them from rising as shown in Fi 4.Said bar I 86 may have at its ends arms I 41 formed oif therefrom andpivoted at I 48 to ears formed on from a frame plate I50. The latter ishere shown fastened to the frame and comb bar 63, which, in this widetotalizer, it serves to stiffen and strengthen.

The means for controlling the locking bar I46 would vary in detail indifierent machines. In the present instance, the left-hand arm I41 isprolonged downward and is connected by a link I5I with a bell-crank I52,conveniently pivoted on the cross shaft 99. Fig. 5 shows a pair oftotalizers one above the other, and the bellcranks I52 of the twototalizers are connected to rock in unison by a vertical link I53. Themachine includes certain parts that are set in distinctive positions fortotal taking, and one of them, viz., the so-called credit balance shaftI54 is utilized in the present instance to operate the locking bail barsM5. As explained in detail in the prior disclosures, this shaft isrocked clockwise in Fig. 5 early in the blank stroke preceding a totalstroke. and is held so rocked throughout the blank stroke and until thelatter part of the total or grand total cycle, when it rocks back to itsnormal position. An arm I 55 is mounted fast on this shaft and isconnected by a link I56 with the lower bell-crank I52 so as to rock thelatter counter-clockwise when shaft I54 is rocked as shown in Fig. 4.This operates the lower locking bail I66 through its link I5I, and,through the link I53, upper bell-crank I52 and link I5I, it

operates the upper locking bar I46, maintaining all of the levers 60locked down during the total taking operation.

As shown in Fig. 6, the link I56 is connected with the lower bell-crankI52 by pin and slot I51 so as to allow the movement of the lowertotalizer into and out of engagement with the racks without rocking thebell-crank. At its forward end said link I56 is connected with the armI55 by pin and slot and spring I58, the spring tending to hold the pinin the rear end of the slot. The motion of the arm I55 is at leastsufficient, when taking a total from the upper totalizer, to take up thelost motion at I51 and to operate the locks I46. When taking a totalfrom the lower totalizer, as shown in Fig. 4, there is an excess ofmotion of the arm I55, which stretches the spring I58.

The mechanism of the invention may be modified in detail and it can beapplied or adapted to various machines without departing from theinvention. The cooperating mechanism of the particular machine which isfragmentarily illus trated in the drawings is fully described in theprior disclosures, but it may be worth while to describe some of itbriefly herein.

Fig. 2 is a sectional elevation taken just inside the right hand framemember H5, and showing some of the mechanism at the right hand part ofthe machine. The total taking control unit I60 contains two cam shafts,one set into rotation to take a total (two cycles) and the other to takea grand total (three cycles). The cams rock counter-clockwise severallevers I6I, pivoted on a post I62. Among these is one which, through oneof several links I63, operates bell-crank I64, link I65, lever I66, linkI61, and arm I68 fast on the credit balance shaft I54, which, as abovedescribed, it was found convenient to utilize to throw in the lockingbails I46 (Fig. 6). This shaft is pulled" at the beginning of each totaltaking operation (early in the blank cycle preceding a total cycle) andis held pulled until near the end of the total taking operation.

The so-called total shaft I10, Fig. 2, is pulled (rockedcounter-clockwise) just before a total cycle by another of the leversI6I acting through one of the links I63, a lever I1I, link I12, one of aplurality of bell-cranks I13, link I14, and arm I15, the latter fast onshaft I10. This shaft performs several functions, one of which will bedescribed briefly.

The grand total shaft I16 is similarly pulled with similar results, justbefore a grand total cycle, by a lever I6I, link I63, lever I11, linkI18, a bell-crank I13, a short link hidden by link I14, and an arm I80fast on the shaft.

The mechanism for rocking the shafts I20 and I2I to move the totalizersinto and out of engagement, is partially shown in Fig. 3, which is aview from the right of parts on the outer side of the left hand framemember II5, the web of said member being sectioned away. Fast on thelower shaft I2I is a lever or arm I8I urged by a spring I82 clockwiseagainst a fixed post I83. The arm I8I is made of two plates connectedtogether by a pin I84 on which, between the plates, four devices arepivoted. Reference number I85 designates a bifurcated link or coupler,the fork of which embraces a pin I86 on the upper end of a followerlever I81 pivoted loosely on a fixed post I88 and drawn clockwiseby aspring I90, against a total taking cam l9I on the front drive shaft 52.The forked coupler I85 is urged counter-clockwise by a spring I92, whichpresses the lower tine of the fork against the underside of the pin I86and holds the upper tine away from said pin. Said upper tine has aratchet-shaped tooth which is normally out of engagement with the pinI86, but can be moved into engagement by depressing the coupler. The camI9I swings the lever I81 rightward at the mid-part and leftward at thelatter part of each cycle. The total shaft I10 is pulled in the latterpart of the blank cycle and, through link I88, pin, slot, and springconnection I93 and bell-crank I84, depresses coupler I85, by means of aroller I85 on said bellcrank. Lever I81, when swung leftward will thenact to rock the shaft I2I counter-clockwise, moving the lower totalizersinto engagement to take a total as hereinbefore described.

Addition on the lower totalizers is controlled by a second lever likelever I81 and just behind it in Fig. 3. The add cam which operates thislever gives the timing appropriate to addition. Pivoted on pin I84 is asecond coupler similar to the coupler I86, but its tooth for cooperationwith the pin like I86, is on the lower tine of the fork and is,therefore, normally in engagement. The total shaft depresses it out ofengagement by a bell-crank like I94.

The upper shaft I20 has fast thereon an arm I96 rocked counter-clockwiseby a spring I61 against the post I83. This arm has pivoted thereto twocouplers similar to those on arm I8I, and operated, respectively, by twofollower levers 200, both pivoted on the post I88 and drawn by springs20I leftward in Fig. 3 to press their follower rollers 202 against therear faces of add and total cams, respectively, on the shaft 52. Thelevers 200 are positively rocked clockwise by their cams, and thecouplers like I85 differ from the latter in acting as pull links insteadof push links. Two bell-cranks I94 (there are four of these in all) areconnected by links to arms fast on the grand total shaft I16. Th addcoupler is normally active, but is depressed out of engagement and thegrand total coupler is depressed into engagement by the rocking of thegrand total shaft I16.

While I have described what I consider to be a highly desirableembodiment of my invention, it is obvious that many changes in formcould be made without departing from the invention, and I, therefore, donot limit myself to the exact form herein shown and described, nor toanything less than the whole of my invention as hereinbefore set forth,and as hereinafter claimed.

What I claim as new and desire to secure by Letters Patent is:

1. In a totalizer in which the transfer of the tens is effected bymoving a totalizer wheel along its actuator relatively to other wheels,a totalizer wheel support settable relative to other wheel supports awayfrom the actuator, so as to disable the wheel on said support bypreventing it from engaging its actuator, and means for concomitantlylocking the support so set against transfer movement.

2. In a totalizer in which the transfer of the tens is effected bymoving a totalizer wheel along its actuator relatively to other wheels,a totalizer wheel support settable relative to other wheel supports awayfrom the actuator, so as to disable the wheel on said support bypreventing it from engaging its actuator, means for concomitantlylocking the support so set against transfer movement, and means alsoacting concomitantly to lock against transfer movement the wheel supportof next higher order.

3. In a totalizer in which the transfer of the tens is effected bymoving a totalizer wheel along its actuator relatively to other wheels,a totalizer wheel support settable relatively to other wheel supportsaway from the actuator, so as to disable the wheel on said support bypreventing it from engaging its actuator, and means acting concomitantlyto lock against transfer movement the wheel support of next higherorder.

a. In a totalizer, a series of totalizer wheels, individual supports forsaid wheels each pivotally movable to sweep its wheel along theassociate actuator to transfer the tens,means for sustain ing saidsupports for said pivotal movement, and means whereby each of saidsupports and wheels is individually settable at the point of pivotalsupport away from its actuator, disabling any wheel so set and makingits actuator free to be operated without turning said wheel whileleaving other wheels operable both to the right and to the left of thewheel or wheels so set.

5. In a totalizer of the kind in which the totalizer wheels are mountedon individual supports each actuated to move its wheel along itsassociate wheel actuator to transfer the tens, a wheel support in theform of a lever having two pivots at different distances from theactuator and settable to either pivot at will, the wheel on said leverbeing engageable with its actuator in one setting and not in the other.6. Totalizer wheels each mounted on a lever' which swing the wheel alongthe rack to transfer, each said lever being individually settable inasaaeao,

the totalizer frame in a direction away from the actuator so as to keepthat particular wheel out of mesh when other wheels engage theiractuators, a tooth on said lever moved by such displacement intoengagement with a tooth on the frame to lock the lever against transfermovement, and a tooth on the lever moved by such displacement over atooth on the lever of next higher order to lock said higher order leveragainst transfer movement.

7. In a totalizer in which the totalizer Wheels are moved along theiractuators to transfer the struction whereby one or more individuallevers may be set at will to an inactive position such that the wheel orwheels mounted thereon cannot engage their respective actuators, and alug on one lever and a lug on the next lever of lower order, the lattersaid lug when its lever is set inactive engaging the former and lockingthe former lever against transfer movement.
